HAIR MAT FOR OlL-PRESSES.

SPECIFICATION forming part of Letters Patent No. 280,393, dated July 3, 1883.

Application filed April 23, 1883. (No model.)

' seeds is accomplished in a hydraulic press by packing the previously-heated seed-meal in a cloth covering that is placed between hair mats secured against the top and bottom faces of the heavy iron press-plates. By the fre .quent use of the hair mats thus exposed to the enormous pressure of about four thousand pounds to the square inch these mats, by

the flattening out of the seed-cakes pressed between, are constantly expanded until after a short time the fibers orhairs will be stretched to a degree that is destructive, and as hair' mats are very costly their frequent renewal adds considerably to the running expenses of an oil-mill.

My invention has for its object to produce a device that will make the hair mats more durable; and it consists in lining the side that is brought in contact with the oil-cake with a sheet of Russian iron secured at its edges by wrought nails driven into the mat.

.I-Ieretofore mats have been made to set in frames, with metal plates secured to and forming a part of the frames. Sheet metal, perforate and imperforate, and wire-clothhave been used to form these plates. Plates thus applied do not form a part of the mat proper, and are bulky and cumbersome.

In the drawings, Figure 1 represents the upper portion of the frame of a hydraulic press as arranged for an oil-mill, and with the pressplates and mats in position therein. Fig. 2is a plan of a mat lined with Russian iron; Fig. 3, a longitudinal section of the same, and Fig. 4 a longitudinal section of one end of the mat on an enlarged scale.

Corresponding letters in the several figures of the drawings designate like part-s.

A denotes the mat, of usual construction, com- 'sian iron, is placed on top of it, and after having been once in the press to adapt itself to the corrugations of the mat, its edges are secured by wrought nails a, driven through perforations of the sheet metal into the mat. A mat thus lined with Russian iron is held from stretching and wearing, and the cakes will not stick to the iron, as theywould to the mat without such a lining, and thereforeare more easily removed from between such mats after having been pressed.

The main object of placing the seedmeal to be pressed out between hair mats is to in terpose a non-conductor of heat between the heated meal and the heavy iron plates of the press, so as not to cool down the seed-meal that otherwise would be in contact with such cold plates. A single thickness of a thin sheet of Russian iron thus stretched over the mat to interpose between such mat and seed-meal will hardly reduce the heat of the seed-meal in 0011- tact therewith for bringing it to the same temperature, while the hair mat still will insulate the material from the heavy iron plates.

What I claim is A mat formed of hair or analogous material for use upon oil-presses, provided on one face with a thin sheet of metal pressed upon and secured directly to said mat, substantially in the manner and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

EDWARD MOYEL.
